lnsertable Containers, ot which the tollowv ing is a speciication.

rlhis invention relates to lubricator vcups and insertable containers.

One oi the objects or" the invention is to improve cups to render theni more econonii- Another object is to protectthe contents ci' the cup from dirt and grit.

Another object is to provide a sealed colas Va shipping package within which to'hold grease or oihior insertion within a cup, tliey contents ot which is not exposed outside of the cup.`

Another object is to provide a new'torm of collapsible, lubricant-container, in co-op- 1 eration with the cup within 'v which it is to be inserted for use. f

Other, further and more 'specilic objects or" the invention will becoinereadily apparent, to persons slrilled'in the-ait, Jtroni a consideration of the following description, when taken Yin conjunction withv the drawings, wherein f Fig. lis an elevation of the improved cup."

Fig. 10 is akey to advance the plunger in the cup to express the lubricant from the container.

In all the views the same reference characters are employed to indicate similar parts.

15 is the main body part of the cup, outwardly flared and enlarged at the bottom, as at 16, having an internal threaded Vopening 17 to provide an oblique shoulder between the two diameters. rllie cup is closed at the top except for the inturned hub 18 which is screw threaded, as at 19, ior the threaded piston rod or stein 20. Stein 20 carries on its inner end a piston, or plunger 21, secured to which is a cup leather 22 and a Afollower 23. rl"he parts mentioned are held in place by a nut 24, the lower end of the steni 2O being reduced, as at 25, and headed at 26.

A key 27, having a rectangular end 28, is insertable in the notch or slot 29 ot the stein 20, for the purpose of rotating the stein and advancing the plunger into the cup.

The grease, or lubricant container 30, is i niade preferably, of collapsib-le material, such as thin sheet lead or an alloy thereof, having inserted at one end a relatively thick and strong disc 31 which is downturned at its end as at 32. The material 33, ot' which the container' is made, is turned around the downturned edge 32, as at 34.

A spring closure 35 is insert-able iii the open end 35 of the container to close the container and to hold thel contents therein during transit, The contents may be either oil or grease.

The lower end ot the cup 15 is closed by a disc 36,'downturned as at 37, at its edges to 'torin anobliqueshoulder at its periphery, and threaded, as at 38, for screwing into the threaded part 17 of the cup.` Discf37is pro vided with an internallyv threadedhub 39 within which is a steni or litting 40. rlfhe lower endet the `fitting vis threadechas at 41.1, for insertion into a'bearing or box to be lubricated. y y i it oil is to-be used in the container 30,

Y then a valve 412 is placed in the bore d3 'of the tit-tinov 4 0. The valve is provided with a re-` and the cap 36 of the cup, to prevent all of` the contents of the container from passing out from the interior of the cup.

Grease or oil is placed in the container 30 and the closure 35 is put into the `opening 35 to prevent escape of the contents of the container. When the container is received and ready for use, the cup 15 is unscrewed from the closure 36. The piston 21 is retracted by rotating the stern 20 in the proper direction. The container is then placed within the cup and the closure 35 is removed from the opening 35. The cup 15 is then screwed onto the end 36, whereupon the ta- Vpered portion 15 of the cup will engage the overlying edges 34 of the container and squeeze the edges into close contact with the downturned edge 32 ofthe disc 3l. This will insure the joint between the bottom wall or disc 3l and the side walls 33 in the container. Now, whenthe contents of the container is to be forced into the bearing, the stem 29 is rotated by the key 27. This has the eifect to contract the collapsible container 30 and force the oil or grease out through the opening at the lower end of the sleeve and into the bearing. If oil is to be used the valve42 is well adapted for the purpose and the rotation of the threaded stem 2O will force a quantity of oil out of the container and into the space in which the valve 42 and theV spring /l-l are located, available for the bearing. If grease is to be used, valve 4t2 is not essentially necessary and the space will be filled with grease, the grease being less mobile than the oil, a special valve to maintain it in the container until required in the bearing, is not of so much importance.

When the threaded stem 20 is rotated the lubricating contents of the container must pass out through the lower end of the valve and not any of it will leak into the cup, and after the container has been entirely collapsed, there is no evidence in the cup that a lubricant has been contained therein, and therefore, the cup is clean andthe lubricant is protected from contact with dirt or grit of any character. After the container has been entirely emptied and collapsed, it can easily be removed from the cup becauseof the fact that the tapered partl permits its coming out without the exercise of any effort in the act of removing it.

,lVlnle I 'have herein shown a single em bodiment of my invention for the purpose of clear disclosure, it will be manifest to per- Y sonsskilled in the art, that Vconsiderable va riation may be madein the general arrangement and configuration of theV parts within the scope of the appended claims.

I-Iaving described my invention what I claim as new and desire to secure by Letters Patent is l. The combination of a collapsible cup for receiving a collapsible lubricant container; a collapsible lubricant container insertable in the cup and having a rigid perforate end wall; means to clamp said end Wall and side wall of the container in the cup and means to contract both receptacles.

2. A cup, to receive a collapsible container, having an outwardly flared screw, threaded, open end and a correspondingly flared threaded closure, in combination with a collapsible container, having an outwardly eX-v tending circumferential extension near its bottom end to be clamped between the flared end of the cup and its closure and having an opening in its bottom, and a plunger in the cup to collapse the container.

3. A cup having anaxially movable piston therein and an outwardly flared screw threaded, open end forming an oblique shoulder; a threaded closure for the cup having a. parallel circumferential shoulder at its periphery; a container of cylindrical form having a relatively fixed centrally perforated vbottom wall of larger diameter than the main body part of said container, the side wallof the body at the bottom end thereof, being extended around'the edge of the bottom wall, thereby forming an extension to be clamped betweenV the shoulder of the cup and ofits closure when the parts are screwed together and a piston in the cup, axially movable to discharge the contents of the container by collapsing the container and a valve in the discharge end of the cup.

t. In combination with a cup, a collapsible container insertable in the cup and having a centrally disposed discharge opening and meansrin the cup to clamp'the container at all points around the opening.

5. A collapsible .container of cylindrical form having a bottom Wall lthicker than its side wall and larger in diameter to form a circumferential projection bywhich to-clamp it within a cup.

6. A one-piece cup shape collapsible con-V tainer having a bottom wall centrally perforated and thicker than the side wall whereby to holdthe container in the cup.

7. A one-piece, cup-shape collapsible con-r tainer having a relatively thin collapsible side wall; a thick perforate end wall, the side wall extending around the edge of the end wall, and a closure foi-.said perforation. In testimony whereof I hereunto subscribe my name.
